The premise
The game is set in the world of Lapis. In short: after the Earth Crystal is destroyed by Veritas of the Dark, Rain, Lasswell and Fina set out to protect the crystals that remain. Square Enix's own storefront blurb, identical on Steam and the Nintendo eShop, puts it this way: "Return to the pixel-art world of FINAL FANTASY, evolved from its classic roots. Travel with companions bound by fate and call on Visions to aid you in battle to uncover the truth behind a force that threatens to bring everything to ruin." That is the whole of the premise as Square Enix publishes it. Past the opening, this page names only what the launch guides confirm, behind spoiler marks.
What this page leaves out
The story runs eight chapters, with a trophy for clearing each; the first is Tailing the Truth and the second Eternal Blue. This page stops at the premise, the cast and the opening, plus the spoiler-marked cards above. It does not describe the ending, the twists or what happens in the later chapters.

Cross-checked on 22 September 2026 against Square Enix's own storefront description and the reporting of Wikipedia, RPG Site, Final Weapon, Kotaku, Noisy Pixel, CGMagazine, Player2, RPGFan, TheGamer, GosuGamers and PowerPyx, and re-checked on 1 October 2026 against Vandal, Eurogamer.es, RPG Site's July trailer report and Nintendo Wire. Re-checked on 22 October 2026, launch day, against the launch guides: IGN's chapter-one walkthrough and walkthrough index, PowerPyx's party-member and trophy guides, the FF Resonance Wiki's walkthrough and Vorxu. Eight chapters: PowerPyx, IGN's walkthrough index and the published trophy list. Chapter 1's name, Tailing the Truth: IGN, the FF Resonance Wiki and Vorxu; Game8 alone calls it Trailing the Truths. Chapter 2, Eternal Blue: IGN and Game8. Nichol, Jake and Sakura as party members among eight: PowerPyx, with IGN's review on Nichol and Sakura; the chapter each joins in comes from PowerPyx alone. The Archwitch, the name the prologue gives the woman you play: IGN's chapter-one walkthrough alone. Not from a playthrough: checked against the sources above. Still to confirm in-game.
